Choosing the right flooring underlay is crucial for comfort, noise reduction, and extending the lifespan of your new floorboards or carpets. This selection focuses on mid-range options offering a balance between performance and cost – ideal for homeowners seeking enhanced sound insulation without breaking the bank. These underlays typically provide good thermal properties, helping to keep rooms warmer in winter and cooler in summer, alongside contributing significantly to reducing impact noise when footsteps are heard.
Mid-range flooring underlay generally consists of materials like PIR (polyisocyanurate), EVA (ethylene vinyl acetate), or felt blends. PIR is a popular choice for its high R-value, providing excellent thermal insulation, while EVA offers good resilience and sound absorption. Felt blends offer a more budget-friendly solution with decent performance characteristics suitable for many domestic situations.
When selecting your mid-range underlay, consider the type of flooring you're installing – hardwood, laminate, or carpet – as this will impact the best material choice. A good underlay will also help to distribute floorboards evenly, minimising squeaks and extending their service life. Always check the manufacturer’s specifications for recommended thicknesses and suitability for your chosen flooring.

FAQ
What's the difference between PIR and EVA underlay?+
PIR (polyisocyanurate) underlay is a foam material known for its high R-value, providing excellent thermal insulation. EVA (ethylene vinyl acetate) underlay focuses on sound absorption and resilience, offering more give underfoot. PIR generally performs better thermally, while EVA is favoured for noise reduction.
How thick of an underlay do I need for laminate flooring?+
For laminate flooring, a minimum of 15mm to 20mm of underlay is recommended. Thicker options (23mm or greater) will offer superior sound insulation and cushioning, particularly with thinner laminates. Ensure the underlay’s specification clearly states it’s suitable for use with your specific laminate type.
Will a thicker underlay reduce noise?+
Yes, generally, thicker underlays provide better noise reduction by absorbing more impact sound. However, excessively thick underlays can sometimes negatively affect the performance of thinner flooring materials like vinyl or laminate; always check manufacturer recommendations.
What's the best underlay for hardwood floors?+
For hardwood, a viscoelastic (EVA) foam underlay with a high density is often preferred. This offers excellent shock absorption and helps to dampen impact noises effectively. Look for an underlay specifically designed for hard flooring to minimise expansion gaps.
Do I need different underlays for carpets?+
While PIR underlay can be used with carpet, EVA or felt blends are often more suitable. Carpet typically doesn’t require the same level of thermal insulation as other floor types, and EVA provides superior comfort and sound absorption beneath a plush carpet covering.
How does underlay affect floorboard squeaks?+
A good quality underlay helps to distribute floorboards evenly and prevent movement caused by changes in temperature or humidity. This reduces the likelihood of squeaks by minimising gaps between boards and providing cushioning against minor shifts.
What is an R-value, and why does it matter for underlay?+
R-value measures a material’s resistance to heat flow; a higher R-value indicates better thermal insulation. For underlays, this means greater ability to retain warmth within the room, contributing to energy efficiency and comfort.
Can I use a thin foam sheet as an underlay?+
While a thin foam sheet might provide some minimal cushioning, it's generally not recommended as a primary underlay. It lacks the necessary density and sound absorption capabilities to adequately protect your flooring or reduce noise effectively.
How does the density of the underlay affect performance?+
Higher-density underlays typically offer superior support, better sound absorption, and increased durability. Density is a key factor in determining how well an underlay performs its intended function – check the specification to ensure it meets your needs.
What should I look for on the packaging regarding suitability?+
Always carefully examine the product packaging for specific recommendations regarding compatible flooring types and thicknesses. The manufacturer’s guidance is crucial to guaranteeing optimal performance and preventing potential damage or issues with your floor covering.
